DUPLEX COUNTING MACHINE.

Application filed Dccember,29, 1923. Serial No. 683,268.

To all whom it may concern:

Be it known that I, CURTIS HUSSEY VEEDER, a citizen of the UnitedStates, residing at Hartford, in the State of Connecticut, have inventedcertain new and useful Improvements in Duplex Counting Machines, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming a part hereof.-

In another application of the present applicant, Serial No. (520,878,filed February 24, 1923, there is shown a duplex counting machine whichhas two counting mechanisms either one of which can be put intooperative relation with the moving part of the machine, the number ofoperations of which are to be registered, so that the number ofoperations dur'ng a given period of time can be registered independentlyof the during another perio of time. In the machine shown in thatapplication two counting machines mounted on parallel axes and eachhaving a driving gear are'actuated through a common shiftable drivingpinion which is in continuous engagement with a driving worm. In thepractical operation of the machine shown in that application it has beenfound that the shifting of the single, common driving pinion from onecounting machine to the other, has a tendency to cause aslight forwardmovement of the counting machine into operative relation with which itis shifted. One object of the present invention is to overcome suchtendency and this is accomplished by mounting on the shifting frame twopinions which are in engagement with each other, one being in engagementwith the driving Worm and the other adapted for engagement with onecounting machine or the other. Another object of the present inventionis to provide means whereby a brake is applied to each counting machineas the driving pinion is shifted into engagement with ing machine. Bythese improvements the accuracy of registration of the two countingmachines is assured. The invention will be more fully explainedhereinafter with referit is illustrated and in which- Figure 1 IS a Viewin front elevation of a duplex counting machine which embodies thecorresponding countf ence to the accompanying drawing in which brake arm'2, which may theinvention with front plate removed, this view beingpartly broken away to save space.

Figure 2 is a view of the same in section on the plane indicated by thebroken line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is a partial-view in section on the plane indicated by thebroken line 33 of Figure 2, looking in the direction of the arrows. I

Figure 4 is a detail view on a larger scale, showing particularly themeans for shiftably supporting the transmitting pinions and the brakemechanism.

Figure 5 is a detail view in edge elevation of one of the brake arms.

The working parts of the improved duplex counter are received within andsupported by a suitable casing a, the front plate a of which is providedwith two sight openings, one of which is shown at a in Figure 3, throughwhich the two sets of number wheels I) may be read. The two numberingmachines may be constructed and arranged to operate in any usual orsuitable manner, as shown for example in the application abovementioned. Each of the counting machines is provided as usual with agear (1 by which" the machine is driven, gears at being adapted to beengaged, the one or the other, by a common driving pinion e which isshiftable into operative relation with one or the other of the gears das may be required. As shown, the common drivin pinion e is mounted on aspindle e, the hu of which is extended at e for a purpose to beexplained. The pinion e is in mesh with a pinion e which is mounted on aspindle e. Both of the spindles e and e are mounted in a swinging yoke fwhich is fixed on a spindle f which has, outside the casing a, anoperating arm f which may be provided with a locking detent i for(Jo-operation with a locking plate The pinion e is in constantengagement with the driving worm h on a shaft It which carries a wormwheel k in engagement with a-worm k on the operating shaft 72..

' Pivoted in proximity to each gear d is a ,be provided with teeth, asat iyfor engagement with the teeth of the gear d. Two brake arms areacted upon by a common spring 5 by which both the two.

brake arms are drawn into engagement with the gears (1. Each brake armis also provided with a cam for co-operation with the extended portion eof the spindle 0' above mentioned. As the yoke f is swung to face thepinion e in engagement with one gear at or the other, the hub e of thespindle e co-acts with the cam surface 5 of the corresponding brake arm71 to move the brake shoe z" out of engagement with the gear a? andthereby release the same for operation. At the same time the other brakearm is caused by the action of the spring i to remain with its shoe z"in operative engagement with the other gear (1. It will be noted thatwhen the yoke f is in an intermediate position, with the pinion e not inengagement with either gear 03, both brake arms 2' will be caused by thespring 11 to move their brake shoes 2" into engagement with the gears(13 and thereby prevent movement of either of the counting machines. Itwill be found that such backlash as exists between the teeth of the twoinions e and e is sufficient to prevent t e transmission of movement toeither gear 03, by reason of the rolling of the pinion 6 upon the Wormh, when the pinion e is moved into or our of engagement with the onegear at or the other.

I claim as my invention:

1. A duplex counter comprising two parallel counting machines, eachhaving a driving gear, a driving worm, a shiftable yoke and. twotransmitting pinions carried by the yoke in engagement with each other,one of said pinions being in engagement with the driving Worm and theother being in operative relation with the driving gear.

' 2. A duplex counter comprising two parallel counting machines eachhaving a driving gear, a common, shiftable driving pinion for operativerelation with one ear or the other, means to drive the driving pinioncontinuously, a shiftable yoke supporting the driving pinion, and brakedevlces actuated by the movement of the shiftable yoke to relieve thedriving gear of one counting machine and to permit a braking action uponthe driving gear of the other counting machine.

3. A duplex counter comprising two arallel counting machines each havinga d iiving gear, a common, shiftable driving pinion for operativerelation with one gear or the other, means to drive the driving pinioncontinuously, a shiftable yoke supporting the driving pinion, engagementwith the driving gears of the two counting machines, and a common springacting upon the brake arms, the brake arms and the shiftable yoke beingin operative relation whereby the movement of the yoke causes one of thebrake arms to release the corresponding driving gear and permits theother of the brake arms to apply a braking action to the other drivinggear.
